Fidget EDC Durandal Slider and Spinner Sacred Sword

Personal Compendium No. 44, Difficulty: ⭐⭐⭐⭐

This project originated from a personal need. I desired a mechanical fidget toy shaped like a sword, balancing aesthetics and functionality. Thus, this sword, christened Durandal, was born. The name is fitting, as Durandal is depicted as a broken sword, impossible to fully draw, mirroring its design. Its internal structure draws inspiration from a distinguished creator's Sword EDC Mechanical Fidget Toy by Qika Mo - MakerWorld design, which I deconstructed and redesigned. Leveraging the unique slicing capabilities of 3D printing, I achieved exquisite texturing and a high level of refinement. However, assembly requires numerous components; thus, I’m open-sourcing it for those who relish a challenge.

PETG printing necessitates adhesive; otherwise, failure is highly probable!

• Required Accessories:

  • Three M1.2 x 6mm countersunk screws
  • Four 2mm x 9mm locating pins
  • Two 3mm glass or steel beads
  • Two 0.3 x 3 x 5 or 0.25 x 3 x 5 springs (length adjustment may be required)
  • One 3 x 6 x 2.5mm miniature free-spinning bearing (available on platforms like PDD in packs of ten for around 11 yuan)
  • Four M2 x 6mm countersunk, pan head, or countersunk screws (countersunk with a hex socket provides a more refined appearance)
  • Two identical screwdrivers for counter-rotating the four M2 x 6mm countersunk screws

• Assembly Steps:

  ① Insert the blade into the handle and secure using two M1.2 x 6mm countersunk pan head screws.

  ② Use four 2mm x 9mm locating pins to secure the parts on the handle, simultaneously installing the gem bezel and gems.

  ③ Insert springs and beads into the blade's apertures. Attach the outer casing with the track, and insert the hollow pillar into the holes for temporary securing.

  ④ Attach the two textured outer plates to the casing, tightening the hollow pillar with four M2 x 6mm pan head screws, using two screwdrivers to counter-rotate them for a robust structure.

  ⑤ Fit the bearing onto the sword's tail and secure it using an M1.2 x 6mm countersunk pan head screw and a locking component.

  ⑥ Finally, attach the rear rotating wheel to complete the assembly.
